30# The two flags "-fpic -DPIC" are used to indicate a
31# will-be-shared object.  Configure will guess the -fpic, (and the
32# -DPIC is not used by perl proper) but the full define is included to
33# be consistent with the FreeBSD general shared libs building process.

156Some users have reported that Configure halts when testing for
157the O_NONBLOCK symbol with a syntax error.  This is apparently a
158sh error.  Rerunning Configure with ksh apparently fixes the
159problem.  Try

209POSIX threads are not supported well by FreeBSD $osvers.

211Please consider upgrading to at least FreeBSD 2.2.8,
212or preferably to the most recent -RELEASE or -STABLE
213version (see http://www.freebsd.org/releases/).
214
215(While 2.2.7 does have pthreads, it has some problems
216 with the combination of threads and pipes and therefore
217 many Perl tests will either hang or fail.)
